Abstract
Objective: Our research was to discuss effects and mechanism of lncRNA TUG1 in NSCLC by vitro study. Methods: A549 and H1299 cells were divided into NC, pcDNA 3.1 and lncRNA TUG1 groups. Measuring cell proliferation using CCK-8 assay, cell apoptosis by flow cytometry, invasion cell number by transwell and wound healing rate by wound healing assay. Relative gene and protein expressions by RT-qPCR and WB assay. Results: Compared with NC group, the cell proliferation rate, invasion cell number and wound healing rate were significantly depressed in A549 and H1299 cell lines (P < 0.001, respectively). By RT-qPCR and WB assay, lncRNA TUG1 gene expression were significantly increased (P < 0.001, respectively); E-cadherin gene and protein expression were significantly up-regulation, and N-cadherin and Vimentin gene and protein expressions were significantly depressed compared with those of NC group in A549 and H1299 cell lines (P < 0.001, respectively). Conclusion: lncRNA TUG1 had effects to suppress NSCLC cell biological activities by regulation EMT relative gene and proteins expression in vivo study.
